Hamster CoT-1 DNA Source?

Hello,
We have been usng Chinese hamster CoT-1 DNA as a competitor in our FISH
experiments for years, however, in 1997 Gibco BRL ceased to produce this
reagent. I have since prepared my own, but this has proved labour
intensive, heavy on tissue culture consumables etc etc.
Does anyone, therefore, know of a commerical source for Hamster CoT-1
DNA? I have scoured catalogues but no joy. Any pointers greatly
appreciated
